Cost & ROI Over Time
A miner pays for itself in profit, not specs. These projections track upfront cost against one, two and three years of net earnings at $0.10/kWh.
| Bitmain Antminer A3 (815Gh) | Metric | Antminer AL1 |
|---|---|---|
| $29,718 | Upfront cost (MSRP) | $10,000 |
| -$3.03 | Daily net profit | -$7.49 |
| -$30,824 | Net after 1 year | -$12,733 |
| -$31,930 | Net after 2 years | -$15,466 |
| -$33,037 | Net after 3 years | -$18,199 |
| Does not pay back at current rates (negative daily profit) | Payback period | Does not pay back at current rates (negative daily profit) |
Projections assume continuous operation, a flat $0.10/kWh rate, and no hardware degradation, pool fees, or BTC price change. Real-world ROI varies.
